Odpowiedź:

[tex] \sqrt{1600} = \sqrt{40 \times 40} = 40[/tex]
[tex] \sqrt{12100} = \sqrt{110 \times 110} = 110[/tex]
[tex] \sqrt{10000} = \sqrt{100 \times 100} = 100[/tex]
[tex]\sqrt{\frac{4}{25} } = \sqrt{ \frac{2 \times 2}{5 \times 5} } = \frac{2}{5} [/tex]
[tex]\sqrt \frac{36}{49} = \sqrt{ \frac{6 \times 6}{7 \times 7} } = \frac{6}{7} [/tex]
[tex]\sqrt \frac{169}{400} = \sqrt\frac{13 \times 13}{20 \times 20} = \frac{13}{20} [/tex]
[tex]\sqrt \frac{196}{9} = \sqrt{ \frac{14 \times 14}{3 \times 3} } = \frac{14}{3} = 4 \frac{2}{3} [/tex]
[tex]\sqrt{1} \frac{24}{25} = \sqrt{ \frac{49}{25} } = \sqrt{ \frac{7 \times 7}{5 \times 5} } = \frac{7}{5} = 1 \frac{2}{5} [/tex]
[tex]\sqrt{5} \frac{4}{9} = \sqrt{ \frac{49}{9} } = \sqrt{ \frac{7 \times 7}{3 \times 3} } = \frac{7}{3} = 2 \frac{1}{3} [/tex]
[tex]\sqrt{2} \frac{46}{49} = \sqrt{ \frac{144}{49} } = \sqrt\frac{12 \times 12}{7 \times 7} = \frac{12}{7} = 1 \frac{5}{7} [/tex]
[tex]\sqrt{3} \frac{1}{16} = \sqrt{ \frac{49}{16} } = \sqrt{ \frac{7 \times 7}{4 \times 4} } = \frac{7}{4} = 1 \frac{3}{4} [/tex]
[tex]\sqrt{0,09} = \sqrt{0.3 \times 0.3} = 0.3[/tex]
